THE WAYS OF OPTIMIZATION PIEZOELECTRIC MATERIAL PZT-19
Different ways to control the properties of the piezoceramic material based on solid solution
system of zirconate-titanate of lead – PZT-19 were explored. Various embodiments of doping to im-
prove the dielectric and piezoelectric properties while maintaining the operating temperature and as
a dopant selected barium cations. Measured and calculated all electrical, piezoelectric and elastic
characteristics. The data obtained allow a computer simulation of piezoelectric elements of any
shape and size, made of modified material for subsequent application in instrument. Conducted re-
search on the stability of the resulting material under cyclic exposure to elevated temperatures. The
graphs of the relative permittivity and the piezoelectric coefficient d33 of the maximum temperature
reached during cycling. A comparative analysis of the properties obtained on a modified material
with the requirements of the industry standard for PZT-19. The new material has improved proper-
ties in comparison with PZT-19, and the stability in the temperature range up to 200 °C.
